42, you shouldn't need any more or less pressure with the modifications that you have, the ECU will adjust around pretty much any small changes in fuel pressure. The only real way to tell is to get something to monitor your A/F ratio, and see what it is at WOT.

ok cool, yea mine also has a guage on it, when would u need to up the psi, what mods would that incorporate with?

I'm no expert but i know i bumped the psi up a little bit after i got my car dynoed and it was running real lean like 16:1 a/f. I still need a new fuel pump though.
